JQuery :: .ajax Success With XMLHttpRequest In 1.3.x?
Jan 15, 2011
My app recently upgraded to 1.4 and as such started using the XMLHttpRequest in the success callback of the .ajax function however we been forced to roll back to 1.3.2 due to performance issues with IE7 (forced to use in a corporate environment) Is there any way to get access to the XMLHttpRequest after an ajax call? If not, would anyone be so kind as to point out if its possible to modify the 1.3.2 source to add the parameter to the success call back like in 1.4? I am hoping its a simple modification however I could be wrong. We are set to upgrade to the lastest jQuery when we get a browser upgrade to IE9 but that could be up to a year away and I would really like to continue to use the XMLHttpRequest in my app as its a lot faster than my old approach.

today I updated my Firefox from 3.5 to 4.0b3 and it seems that the AJAX success callback is not longer fired. Firebug shows the correct response but the function is never called. Is this a Problem of the FF Beta, or is Jquery responsible for this?
Here is my Script
$.ajax({
url: 'ajax.php',
success: function(data) {
console.log('success');
[Code]....

This is the exemplar I've been using for my $.ajax requests to my php script.
$.ajax({ type: 'GET', url: 'getDetails.php', data: { id: 142 }, success: function(data) {
// grabbed some data! };
});
I'm working with a few more variables than this, I'm working with 3 variables. What I'm wondering is should I use json_encode() on the php side. I will be using php validations, so I may return error messages in an array. How do I check whether I have error messages or true value.
I'd like to send in an associative array so I can have email = "error"; amongst a few others. So if email is the only one with error I will .append a message to the correct div id.

I'm so happy my jquery is dispatching a serverside script (ajax) and it is working I have verified in the database.Now I would like to provide some feedback to the user so first go will be alert, later I will do something snazzy.I am just getting head around jQuery, so please excuse noobness of question. I will think that either one or the other of these alerts below would fire, but neither of them do and nothing also logs in the console.

I've noticed this weird behaviour of jQuery in Safari and Chrome (didn't test on Firefox as I'm using some webkit CSS extensions). After setting up the call like this:
$.ajax( {
'url' : url,
'dataType' : 'json',
data : reqdata,
cache: false,
method: 'get',
timeout: 20000, //10 secs of timeout
success : function(data, textStatus, XMLHttpRequest) { .....
If a timeout occurs (I switch the local webserver off), the 'success' method will be called! More than this in the textStatus parameter there is a string with "success" !!! The error handler doesn't even get called.... (As you may notice the only way I had to tell the problem, was to check the data param if it is null or 0 length. How can I avoid this?

I used to call web service with parameter like this and works fine.
function InvokeRequest(Url, Param, SuccessCallback, ErrorCallback) {
$.ajax({
type: "POST",
url: Url,
[Code]....
But instead of firing the success callback, it alert the result 200 ok with the JSON result.

When using .ajax, and when before I receive any data back from the server, I would like to call a function that could display some type of 'thinking' icon. In looking a the documentation I see there is a 'success', for when after receiving data back successfully, and an 'error', for obviously when something bad happens and need to error gracefully. I do not see something like a 'beforeSuccess' function that would allow me to specify, for example, to overlay a 'thinking icon' on top of a <div> after request is sent to the server and before I get any data back. I would assume this is a pretty standard necessity in ajax applications, and probably missing something here. How exactly is this done using the .ajax methods?

I would like to submit a form depending on the success data of an ajax post.
Below is my jquery code; as you see #theform is the main form and before submitting the form I need to check the availability of the the date and time and the room using$.ajax. However it doesn't submit the main form if the date, time and the room is available.
required=["txtCal_Event_CalendarID","txt_TreatmentRoom","txtTreatmentID","txtTreatmentTypeID","datepicker1","datepicker2","timepicker1","timepicker2"];
emptyerror="Please fill out this field.";

I find ajax with jquery more confusing than with regular JS, b/c in jQuery you don't declare XMLHttpRequest object.. so how do you do something like:
In example I mention here,[url] namely [url] I don't understand where var 'msg' is declared, I know it comes from the back-end, but HOW is it passed to the front-end? (how do you do this w/o responseText or something similar?)
I'm trying to connect to a send-mail jsp with ajax.. the email is not getting sent.. I want to test if the ajax connection is being made at all.. don't know how do it w/o something like xmlHttp.responseText
This is my jQuery ajax code for connecting to send-email jsp:
var dataToSend = "name=sName&email=sEmail&msg=sMsg;

It is day two of the same problem (and day two of learning Ajax, day five of Javascript)
The current code (below) does nothing; it does not go into the showContents function. Switching the order of some items would cause it to enter the function, but it would always alert that the xhr status was 0. I guess this is an improvement?
php doc that is getting requested (I don't think the error is here as the problem is that it is not even initializing):
Code:
javascript code that is requesting the information:
Code:
I need to pass the num variable because the fields I am dealing with are part of a bunch of fors that create an unspecified number of fields titled 1source, 2source, 3source, etc.

I am trying to create an xmlhttprequest object to update the shopping cart on my web page without submitting the entire page to the server for processing. However, what I have done so far is not working. All that is happening when I click the "update cart" button is the page sort of flashes and the check marks in the remove item check boxes disappear. The first code snippet is the "traditional" way of submitting the whole page to the server for processing - and it works. The second snippet is what I have done to try and implement AJAX to submit only the shopping cart - and it does not work.

I am trying to build a very simple Ajax example with JavaScript and PHP. Basically, the goal is to populate a select list with values dependent on the selection in another list. I am able to do a GET from a server-side script and I see the XML displayed correctly in XMLHttpRequest.responseText. However, when I try to check XMLHttpRequest.responseXML, I am not able to get anything out of it. The alert() shows it as an "Object", so it's not null. I have tried getElementByTagName() from both responseXML and responseXML.documentElement, each time giving a legitimate inner tag, but nothing comes out. What is the correct way of doing it? This is my JavaScript and HTML code:

i am new to AJAX but i havejust managed to write one of my first basic scripts. What it does is takes all the news items out of a database and lists them as links. When you click a link i want all of the data that is linked to that news item to display underneath. Now i have got this to work except it will not work in Firefox, all other browsers it is fine.

I was wondering if it was possible to execute javascript returned by ajax (XMLHttpRequest)? I can see that the script is returned by it doesn't execute. Here is what it returns. I can see the output but when I click on it nothing happens.

function hi(name){
var latBox = document.getElementById("myinfo");
latBox.innerHTML = "<div>Greetings: " + name + "</div>";
}
</script>
<p onClick="hi('hi');">Math.random = " + Math.random() + "</p>
